I was wrong about going off and coming back. The last two times I’ve produced the error were right after I booted up the thinkpad. Could be iPad power saving related, but I’m amazed it crashes the thinkpad’s network. Reminds me of the ping of death.
Before a network crash:
[root@thinkpad ~]# ethtool wlp3s0
